The caption for the photograph goes:
"A wary Kalinga warrior watches over a bend in the Chico river, north of the Luzon mountains. The Kalinga were enraged by plans to dam the river, at a cost of several villages and rice terraces, and the inundation of ancestral graves. Though they no longer display enemy heads on posts, the Kalinga are not to be tangled with."
